refactor: enhance theme and error handling across the application

- Updated error handling in EnhancedErrorService to utilize context for color tokens, improving theme consistency.
- Refactored various components to use context-aware shadow and color properties, enhancing visual coherence.
- Replaced hardcoded color values with dynamic tokens in multiple widgets, ensuring better adaptability to theme changes.
- Improved overall code maintainability by centralizing theme-related logic and reducing direct dependencies on static theme values.
